' Sa -awesome .MAGH N llppl ica'tion'nled August 14,1825. 'Se'ria1 iNo.o;29;8.'

This invention relates to sheet metalforming machines, and particularly to ama'ehine for turning edgesoni caps and' bonnets of drive shaft. I i I 'FigureS is a detail oftheend" of the drive sheet iron.

An object of this invention isto provide a machinejadapted to turn the edges on ca s and'bonn'ets of sheet ironand set downt esame for double seaming and to accomplish the double functioni'n a .single maehine.

A further object of this invention is; to provide attachments (for an ordinary bed which are adapted to perform the aforesaid funetionsin simple and easy manner.

VVith the foregoing andother objects in- View, have invented-the device shown' in the accompanying'drawings, in whioh:

Figure 1 is .a side elevation of 'my improved machine.

Figure 2 is a top plan view thereof. Figure 3 is an end elevation thereof.

Figure 4 is a detail'of a portion of the shaft.

Figure 6 is .a section at 6.,6 offFigure 5. Figure 7 is an end roller., 1' a t Figure 8 is a side elevationpartly insection of the roller shown in Figure7 Figure 9 is a side elevation of-theshaft journal "support member "detached.

"Figure 10' is a like view to 'Figure9, at

right angles thereto. v I

; Figure his a section at 11%11 of Fig Like reference characters indicate 'like parts throughout the several views and in the specification, in which there is provided a table "2, which maybe of the usual form of table, carrying head 3, which journals a pair ofshafts 4 and 5 passing through the head 3 and drivenby (so-meshing gears 6, and

7. which gears in return, through a train of-gears-S drive a. gear 9, which gear 9' is afiixed to a shaft 10, which shaft 10 passes beneath the table 2 and is journaled in the ends of thetable, the table 2 being supported by legs 11. i

Slidably mounted upon the table 2 is a turret 12 carried by a plate 13 and clamped in predetermined positlonsupon the table 2 by a clamp lever 14. Slidably mounted upon the shaft lO and carried by the plate 13 is a bracket journal 15, earr ing therewith a bevel. gear 16; the shaft 0 being provided elevation of a shaping 1 bars27*aresupported byza transverse plate -With :a' longitudinal key extending} substantial-ly the entire length of the shaft 10; and

the bevel gear 16 being -s lid'ab1e 'upon the key; and adapted 'tobe turned by the key uponth'e shdft 10. Carried depending from the turret 12'is a'vertical shaft '17 journaled in '{a'vertical "conical bearing member 18 and a flixedto the turret 12 so vas to rotate the turret therewith, and carrying at its lower end bevel gearfl-9, which bevel -gear 19 co- -meshes with the bevel "gear 16 and moves in meshwith the gear l6 -upon the sliding of the 1 plate 13 upon the bed-or table The i turret=12 is adaptedito carry the disk or cap or other work to beperformed whieh is held roller 20 is adjustable upon-a loar'21 :sup-

ported by aabracket 22, the adjustment being setby a wing-nut -23. Attheside of the turret '12 is a further-guide or work support roller -24=fladapted engage the flang ed edges of the work as oarried upon the turret 12; the roller 24: being supported 'by a shaft 25, %the"shaft"25 being carried -by a bracket :26, thebracket '26 'slidableupon a bar 27, there being two of the bars 27, which adjustment '29 for suitably spacing the bars apart in a desired or predetermined relation. 1A Eforming roller 3O is carried byy-a {shaft {31; which shaftBl-i's j our'na'l-led in a vertical- 1vmovable bearing box 32, and is provided With a universal joint 33, Wvhieh shaft P is shown, more in detail i i Figure 4; the' universal oint -33 having extending therefrom a stub shaft' 'e'lement 34-over-whiohis a sleeve 35 longitudinally slideable upon the stub whereby ithe sleeve 35 may have i a longitudiv *nal moveme t relative {to the stub shaft -34,

but' will rotate with -theshaft- 34;fthus pershaft "'34 'and" anchored thereto {to rotate Y therewith by a pin 36 'slideable in I a 'slot' 37,

tation and contact with the work will not loosen them from the shaft 39. The journal member 32 comprises a sleeve 42 into which telescopes a sliding shaft 43 carrying a transverse journal boX' 44 extending in hublike formation as at 45, and depending from which hub-like formation is a rod 46.. Car ried integral with the sleeve 42 is a boss 47 providing a sliding bearing for the rod 46, and beneath the boss 47, upon the rod 46, is carried a helical spring 48 which yieldingly holds a bearing element 44 downwardly relative to the sleeve 42. Aflixed to the sleeve 42 is a yoke 49 by bolt members 50 passing through the terminals of the yoke 49 and into bosses 50 carried by the sleeve 42. Passing through the middle portion of the yoke member 49 is an adjusting screw 51 turned by a crank 51 which adjusting screw seats in a boss 52 above the journal portion 44 so that, upon the turning of the crank 51, a vertical adjustment may be had in one way against the yielding of the spring 48. Further angular adjustment may be ob tained by mounting the journal member 32 to rotate about a pivot 82 on a standard 82 secured to table 2, and by providing said member'with a clamping screw 53 extending through arcuate slot 54in said standard 32 to clamp the journal 321to said standard 32 in any desired angular position.v

Carried by the shaft 31 may alsobe cutting disks such as 55 which may likewise cooperate with elements carried by the shaft 5 for any desired formingor cutting opera-.

tion. Carried by the table 2 is also a work support roller 56. i

In operation, whcnpowcris applied to the shaftv 4 by the co-meshing of the chain of gears, the shaft 10 is also driven by like power so, that the turret 12 rotates simultaneously with the forming wheel 30 in the wdesired or predetermined speed ratio and the workcarried by the turret 12 is suitably formed by the forming wheel 30. It is obvious that any of these elements may be quickly slid from the table 2 and other suitable elementsplaced in position.

I claiIn- -1. In combination in a sheet metal formcarrying the forming wheel, mechanism for vertically and angularly adjusting the shaft,

and means for locking said mechanism and shaft in adjusted position.

2. In combination in a sheet metal forming device, a turret for carrying the work to be formed, a formingwheel, a shaft carrying the forming wheel, means for vertically and angularly adjusting the shaft relative to the turret, and means for simultaneously r0tating said turret and shaft.

3. An adjustable journal member for a sheet metal forming roll shaft, including a member adapted to journal the shaft and having a cylindrical part depending therefrom, a sleeve in which said part is slidably mounted, a yoke carried bythe sleeve and extending above said member, an adjusting screw threaded into said yoke and engaging said member to move it relative to Said sleeve, and yielding means between said sleeve and member to maintain said member in contact against said screw.

4. A sheet metal forming machine, comprising a bed, a standard fixed to said bed, a turret slidable on said bed toward and from said standard, a bearing, means for vertically and angularly adjusting said bearing on said standard, a shaft rotatable in said bearing, a forming wheel on said shaft, and means for rotating said shaft at all positions of adjust- I ment of the said bearing.

5. A sheet metal forming machine comprising a bed, a standard fixed to said bed,

a turret slidable on said bed toward and from said standard, a shaft rotatable on said standard, and having a forming wheel at one end thereof, means for vertically and angularly adjusting said shaft on said standard,

means for clamping said shaft in angularly ad usted positionon said standard, and means for rotating said shaft in all positions of vertical and angular adjustment thereof.

6. In a shaft ad usting inechanisn'i for a sheet metal. forming device, in combination,

a. member adapted to journal the shaft and provided with a depending cylindrical memher, a sleeve in which said cylindrical memberis mounted, a boss carried by the sleeve, 2. rod depending from the journalmember and slideable in the boss and having a nut at the free end thereof and a spring betweensaid boss and nut.

In testimony whereof I atlixmy signature.
